[Icom] Icom 2000 Molex Connector

[John Luthy]

Hi Mike,

As I understand. it is to protect the radio from ground failures in
the auto.  As you have the radio power connected directly to the
battery, if there is a fault in the vehicle ground the "juice" will
try to find ground anywhere it can. (Remember how  you made sure you
had a good ground at the radio and the antenna?) That means your radio
could serve as the ground path for your starter! Ouch 200+ amps could
never be good for a piece of ham gear!  Let alone the 14 guage wire
would become blazing hot and melt all of the insulation filling your
auto with the rancid smell of burning plastic.

As a note I have seen things like throttle cables, choke cables, ect,
carry the load for ground. Needless to say you can imagine that a
throttle cable that has gotten red hot might just "weld" itself in to
position, that would not be a good thing either!
